OF ELMIIRA, NEW YORK, A CORPORATION OF NEW YORK.

FOLDING PAPER BOX, BOX CORNER, AND BLANK THEREFOR.

' Application filed April 8,

To all whom it may concern:

Be it known that I, HARRY Bonn ALLEN, a citizen of the United States,residing at Elmira, in the county of Chemung and State of New York, haveinvented certain new and useful Improvements in Folding Paper Boxes, BoxCorners, and Blanks Therefor; and I hereby declare that the following isafull, clear, and exact description thereof, referencebeing' had to theaccompanying drawings, which form part of this specification.

My invention relates to folding paper boxes, and box corners and blanksfor forming the same. I

The object of my invention is to improve, simplify, and cheapen the costof construction, to eliminate waste incident to shaping the folds andfastenings provided for in the blank from "which the box is set up.

It is also my object to provide an improved rectangular box-cornerdesigned to form an integral union of bottom, sides, and embody thereina fastener to hold said parts together at rightangles to each other.

In the accompanying drawings forming a part of this specification Figure1, is a plan View of a blank for the box. Figure 2 is a perspective viewof the box, and Figure 8, is a detail of thebox corner.

Referring more particularly to the drawings: A, denotes the bottom ofthe box. B, B, the ends, and C, C, the sides of the box. The ends B, B,terminate in tongues Z), 7). Z), Z and each tongue is slit or bifurcatedforming latches 7) adapted to overlap by forming at the base of eachlatch scores 6 7F. formed in the tongues 6 below said slits; said scoresbeing projected at obtuse angles to said slits in opposed diagonal linesbelow the base of each latch, as shown in the drawings. The purpose ofsaid scores is to facilitate the lapping of one latch over the otherwithout danger of tearing off the latches, and moreover said scoresaffect the spreading of the latches apart after they have been passedthrough slits 0 located in the sides C adjacent the corners. and whichare designed of a width to receive the latches when folded one over theother, and when spread apart to afford a hold for the latch dogs 5 Thebox and corners are readily set up Specification of Letters Patent.

from the blank by folding the sides at rightangles to the bottom,likewise the ends; the tongue latches are thus presented opposite theslit in sides B and manipulated from the outside of the box. The foldsto form the corner are manipulated as follows, first the side Ccontaining slit 0 is folded at rightangles to the bottom A, then the endB is likewise folded and the tongue Z) passed outside. around the cornerthus formed in outline. In this position the ends of the latches b willproject beyond slit 0 while the locking edges of dogs 6 will meet saidslit 0. Thelatches Z) Z) are then pushed back until their ends meet slit0 preparatory to their entrance therethrough. The effect of saidbackward movement of latches b b will cause the body of the tongue andbase of the latches to be raised upward in tentlike shape following thelines of the diagonal scores b 5 said diagonal scores being designed toallow and facilitate said movement of the tongue. The dogs Z2 6 are thenoverlapped, directed to the slit 0 and then forced forwardthrough slit 0by pressing down upon the said raised portion of the tongue.

I claim- 1. A collapsible box-corner formed of a blank embracin inintegral relation the bottom, a slitted side, and an end portionterminating in a divided tongue which tongue divisions are adapted tooverlap each other and enter said slitted side; said end portion havingscores positioned at an obtuse-angle to the base of each tonguedivision, said bottom, sides, and ends being adapted to fold atright-angles each to the other.

2. In a fastener made of sheet material, a tongue slit longitudinally toform latches and scored at an obtuse angle to the slit, and a memberhaving a slit to receive the tongue.

3. In a fastener for paper receptacles a tongue slit to form twolatches, said latches scored diagonally adapting them to overlap eachother.

In testimony that I claim the foregoing as my own, I affix my signature.

HARRY BUDD ALLEN.
